This product is fully biodegradable using industrial composting techniques. heat aeration and finely shredding the material. 

It can be collected and placed in the green organics bin in a number South Australian council areas.

PLA is inexpensive, easily available and comes in a wide range of colours and textures. It has Australian manufacturers, requiring less carbon miles. 

​

PLA combined with wood fiber is more quickly degraded but still requires industrial techniques. 

​

A preferred type of filament is PHA . it is derived through natural fermentation. This product is home compostable and biodegrades in all biotopes including marine environments.

The brand I can currently source is allpha and manufactured by colorfab in the Netherlands. It is expensive and not always available with Australian distributors.
